One of Colorado鈥檚 top water officials says he cannot enforce recent federal demands to start conserving more on the Colorado River.

State engineer Kevin Rein oversees the state鈥檚 water rights system. In a meeting with the Colorado River District board on Jul. 19, Rein assured members he would not be mandating conservation among their municipal, industrial and agricultural users. The district covers 15 counties in Western Colorado.

鈥淭here is nothing telling me to curtail water rights. There鈥檚 nothing telling me that I should encourage people to conserve,鈥� Rein said.

The federal government recently called on the seven states that use the river to curtail their uses by two to four million acre-feet to keep the Colorado River鈥檚 largest reservoirs 鈥� Lakes Mead and Powell 鈥� from declining to dead pool levels, and threatening the drinking water supplies for tens of millions of Southwestern residents.

Colorado officials have argued the blame for the river鈥檚 supply-demand imbalance rests with California, Arizona and Nevada. Some doubt the federal government鈥檚 authority to demand the states use less water. The 1922 Colorado River Compact, a document that inflated available water within the entire basin, apportioned 7.5 million acre-feet of water to the river鈥檚 Upper and Lower Basins, respectively. In recent decades Lower Basin uses have exceeded that amount, while Upper Basin uses have remained below the apportionment.

鈥淲e鈥檙e way under our allocation of 7.5 million acre-feet a year,鈥� Rein said. 鈥淪o what does that mean? 鈥榃e need to conserve.鈥� To me, that means that we don鈥檛 change our administration at the state engineer鈥檚 office.鈥�

Rein said he has mandated water use reductions in other Colorado watersheds under the compact administration legal process. But the Colorado River has avoided that fate so far, he said. Without a solid legal basis, Rein said his hands are tied.

鈥淚f you have a beneficial use for water and you have a right to water and the right is physically and legally available, then I would encourage people to use your water right. It鈥檚 a public resource. It鈥檚 a property right. It鈥檚 part of our economy. It鈥檚 part of your livelihood,鈥� Rein said.

鈥淪omebody might tell me I鈥檓 wrong someday, but right now, I don鈥檛 see a legal basis for asking people to curtail,鈥� Rein said.

Federal officials continue to paint a bleak picture for Colorado River reservoirs without unprecedented amounts of conservation over the next year. The Bureau of Reclamation runs a 鈥淧rotection Volume Analysis,鈥� which gives an amount of conserved water needed to keep Lake Powell and Lake Mead at specific target levels.

During the same Colorado River District meeting, the Bureau of Reclamation鈥檚 Upper Colorado River assistant regional director Katrina Grantz laid out the agency鈥檚 rationale for asking for two to four million acre-feet in conservation. She said the cutbacks should come from all corners of the watershed and all sectors of the economy.

鈥淚t鈥檚 states, it鈥檚 tribes, it鈥檚 water districts, it鈥檚 cities. In order to achieve this, we need to look broadly, and we need to look creatively,鈥� Grantz said.

Colorado River District general manager Andy Mueller said he wanted to know how the federal government was planning to tighten how it accounts for water use in the Lower Basin, including evaporation from reservoirs, a longtime complaint of Upper Basin leaders.

鈥淚t is extremely frustrating to see system water utilized for the benefit of the three Lower Basin states and us taking a hit for it. And now we are for the first time, frankly, about to be injured by it,鈥� Mueller said.

Upper Basin leaders have resisted calls for specific amounts of conservation on the Colorado River. In a plan released last week, the four Upper Basin states 鈥� Colorado, Wyoming, New Mexico and Utah 鈥� instead call for the reinstatement of a conservation program that paid farmers to forgo water supplies, first tested in 2014.

鈥淭here鈥檚 a lot of mistrust up here,鈥� said board member Marc Catlin, a Republican member of the Colorado House of Representatives. 鈥淭he idea that we鈥檙e going to tell you how much we can save allows [the Lower Basin] to decide what they鈥檒l do. It seems to me that somebody at the Bureau of Reclamation has some goals laid out for the Upper Basin, and we鈥檇 like to know.鈥�

A Bureau of Reclamation reservoir forecast in August is set to steepen the existing cutbacks among Lower Basin users. If current projections remain, the Lower Basin will enter a Tier 2 shortage condition for 2023, deepening cuts to users in Arizona, Nevada and Mexico.
